`"PEP" is short for Telebit's "Packetized Ensemble Protocol". It is the
`method by which they divide the telephone bandwidth into 512 discreet
`slow carriers on which they transmit the data, and the key to their
`being able to get high throughput.

` "PEP" stands for "Packetized Ensemble Protocol", the transport protocol
`used with Telebit's proprietary multicarrier modulation technique ("DAMQAM":
`Dynamically Adaptive Multicarrier Quadrature Amplitude Modulation). Quite
`often "PEP" is used where "DAMQAM" would be technically correct but, in the
`case of Telebit modems, the two work hand in hand.
